Title: Improvements in and relating to permutation locks
Inventor: STANTON WILLIAM HENRY
IPC: E05B37/08
Filed: 1957-11-27
Abstract: 850,834. Permutation locks. CHUBB & SON Ltd. Nov. 14, 1958 [Nov. 27, 1957], No. 36995/57. Class 44. A permutation lock comprises a bolt 2 and bolt lever 4, a driver 10 operable by a spindle 9 and engageable by the bolt lever for the purpose of operating the bolt and control wheels 6 adapted when preset to unique angular positions to allow engagement of the bolt lever with the driver but in all other positions to prevent such engagement, wherein the driver is loosely mounted on supporting means 5 other than the spindle and the spindle is axially movable between one position where an abutment 13 thereon is firmly engaged with the driver and another position in which the abutment 13 is disengaged therefrom. As shown the supporting means 5 is a tubular post through which the spindle 9 projects and which carries the wheels 6. On the end of the spindle 9 is a disc 11 provided with the abutment 13 which when the groove is moved axially towards the driver by means of the spindle engages a peripheral slot 14 in the driver so that the driver can be rotated by the spindle. Each side of the slot 14 has inclined cam surfaces 15 so that if the disc 11 and driver are slightly out of alignment the axial movement of the disc 11 will cause the driver to rotate into alignment by engagement of the abutment 13 with one or other of the surfaces 15. The driver is provided with a recess 16 in which a hook of the lever 4 can engage for actuating the bolt and the disc 11 is provided with a slot 17 adapted to engage an abutment on the inner surface of the rear cover plate of the lock when the spindle 9 is pushed axially inwards, to prevent rotation of the spindle in that position. This abutment rides against the rear surface of the disc 11 while the spindle and disc are in their forward axial position to prevent inward axial movement of the spindle until the slot 17 becomes aligned with the abutment. The lever 4 is normally held out of engagement with the edges of the control wheels and driver by means of a snap action character as disclosed in Specifications 735,148, 748,360 or 815,654.

Abstract: 363,805. Davits. DINGERTZ, K., 23, Brahmsallee, Hamburg, Germany. Dec. 9, 1930, No. 37085. Convention date, Oct. 14, 1930. [Class 115.] Ships' davits of the luffing gravity type comprise a rigid davit arm pivoted to a rigid system presenting a stop against which the davit arm first abuts on release of the suspension rope whereupon further rocking of the rigid system about a second pivot located further outboard results, the two units moving as one during this second phase. A davit arm 1 is pivoted at 2 to a framework 3 which in turn is pivoted to the ship at 4. In the inboard position the arm 1 rests against a stop 5 and the boat abuts on a stop 11. As the falls 7 are released, the arm 1 pivots about 2 until it abuts at 12 on the second frame. During the next phase of movement the system as a whole rotates about a pivot 4. The system is restrained by a tension member 6. During the outboard pivoting movement, the pulley 9 is held at the outer end of the arm 1 by a curved arm 15, but becomes free for lowering the boat thereafter.

Filed: 1958-11-19
Abstract: 849,176. Testing cable insulation. OKONITE CO. Nov. 19, 1958, No. 37234/58. Class 37 The insulation of an electrical cable is continuously tested by passing it through an insulating tube having earthed plugs at each end and a condensable vapour filling the tube so that it condenses on the surface of the insulation to form a slightly conductive film there. A high voltage source is connected between the central conductor of the cable and an electrode in the insulating tube so that the insulation of the cable is subjected to a dielectric stress the ionization characteristics of the insulation being continuously observed as the cable passes through the tube. The Figure shows an apparatus for testing insulation of an electric cable 2 the central conductor of which is grounded at the reel 12 from which it is fed via an insulating tube 4 on to the take-up reel 14 at which also the central conductor is earthed. The insulating tube 4 is provided with earthed stuffing boxes 6 at each end and is filled with a condensable vapour such as wet steam which condenses on the surface of the insulation and is finally collected in a sump near the centre of the tube. Contact is made with the cable at the centre of its passage through the tube 4 by means of an electrode 8 and contact roller 9. High voltage from a transformer 20 is connected between the electrode 8 and the earthed centre conductor of the cable and the ionization characteristics of the insulation are observed by a radio receiver 34 and a recording galvanometer 40 connected to the electrode 8. By adjustment of the voltage from transformer 20 the characteristics of the insulation at varying stress voltages may be found.

Filed: 1963-09-25
Abstract: 1,072,525. Fluid-pressure servomotor systems. ELLIOTT BROS. (LONDON) Ltd. Sept. 21, 1964 [Sept. 25, 1963], No. 37795/63. Heading G3P. A hydraulic actuator comprises four hydraulic units arranged symmetrically around an output member 28a, (the drawings shows a flat development of units). Each unit comprises a valve 18 actuated electrically to control the supply and exhaust of fluid to a line 17 to act on the left hand side of a piston 6, the right hand side being connected to the pressure line through a passage 16. A rod 10 extends from the piston and fluid pressure is fed through a passage 14 of the rod to urge two ferrules 25, 26 against stops on the rod and a sleeve 29, the sleeve normally being coupled to a block 28 by balls 33 urged outwards by a piston portion 34 of the rod 10. Bevelled recesses 45 are provided on the sleeves 29 and discs 43 normally partly engage these recesses in two adjacent sleeves. If a failure of one unit occurs, as shown in the bottom unit, the piston portion 34 releases the balls 33 and the sleeve 29 moves relatively to the block. Such movement causes the two discs 43 associated with this sleeve to move further into the recess of the adjacent sleeve. When failure of all units except two has occurred, the discs 43 are pressed by the sleeves and each other to lock the sleeves of the remaining two units together thus preventing disengagement if a further unit fails. Switches 30 connected to lamps 31 indicate a failed unit. The system may be used to actuate an aircraft control surface in response to manual control.or altitude. A position indicator 15 of the piston 6 provides an electrical feedback to the input members 21.

Title: Electric fuel-injection control systems
Inventor: WAKATATSU HISATO
IPC: F02D41/36
Filed: 1969-07-29
Abstract: 1,273,793. Fuel injection control systems. TOYOTA TIDOSHA KOGYO K. K. July 29, 1969 [Aug. 7, 1968, Sept. 10, 19681, No.38015/69. Heading G1N. In an I. C. engine fuel injection control system, the duration of opening pulses for the electromagnetically controlled injection valves, is controlled in dependence upon the back pressure in the inlet manifold and the engine speed, and are supplied to the electromagnetic valves 2-5 in a sequence according to a signal synchronous with the engine speed. As shown, the output pulses of a monostable multi-vibrator 9 have constant width and amplitude and a recurring frequency dependent upon the back pressure, this output being combined, in a sawtooth generator 10 including an integrating and switching circuit, Fig. 3 (not shown), with the output of a pulse generator 11 producing pulses of a frequency synchronous with the operation of the injection valves and thus the engine speed. The sawtooth output has a slope and frequency dependent upon back pressure and engine speed and is applied to one input of two differential amplifiers 13, 14, the other inputs of which are supplied with a reference voltage from a frequency/voltage converter of the output of generator 11. When the accelerator is depressed, the back pressure decreases, and the slope of the sawtooth wave decreases and its frequency increases. During the period when the sawtooth output is lower than the reference voltage, an opening pulse is supplied via distributors 15, 16 and driving units 17-20 to one of the electromagnetic valves 2-5. When the sawtooth output is the same as the reference voltage the pulse is ended. If now the accelerator is eased off, the back pressure increases, the slope of the sawtooth increases and its frequency decreases, and the reference voltage decreases and therefore the duration of the pulses supplied to the electromagnetic valves decreases. In an alternative, Fig. 7 (not shown) the output of the oscillator 8 having a frequency dependent upon the back pressure is converted into a D. C. signal which is then corrected by the signal from the generator 11 to produce a reference voltage. This reference voltage is applied to one input of four differential amplifiers, one for each electromagnetic valve, to the other inputs of which is applied the output of a respective sawtooth generator triggered by the signal from the generator 11.
